Iyo Raspberry Pi Foundation yakaburitsa yayo yekutanga Pi Pico microcontroller bhodhi munaNdira apfuura, ichidhura chete $ 4. Kubva pane hwaro RP2040 SoC, iyo Pi Pico yakatotengesa 250.000 makopi uye 750.000 yakarairwa.
Pamusangano wapfupi mudiki weML Talk, iye mubatanidzwa weiyo Raspberry Pi hwaro, Eben Upton, akapa rumbonera mune ramangwana repuratifomu. NaPi Pico, hwaro hwaratidza kufarira kwaro kungwara kwekunyepedzera Uye inotevera iterations inotarisirwa kuunza zvakakosha kuvandudza kumuchina kudzidza.
Masiraidhi akaunzwa naEben Upton pachiitiko ichi anoratidza kuti Pi Pico inogona kushanda sedziviriro yekuumba mabhodhi akasarudzika ekudzidza kwemuchina (ML).
Zvechokwadi, Pi Pico idiki uye risingadhuri kadhi inosanganisa iyo RP2040 system pane chip (SoC) yakagadzirirwa nenheyo pachayo.
Iyi SoC inosanganisa mbiri-musimboti Arm Cortex-M0 + chip iyo inoshanda inosvika 133 MHz, iine 264 KB yeiyo static random yekuwana memory (SRAM) uye 2 MB yeboardboard yekuchengetera. Diki saizi (21 x 51 mm), iro kadhi zvakare rinosanganisira chiteshi cheUSB chine 26 I / O pini.
“Ini ndinofunga zvinogona kuitika kuti pane chimwe chidimbu chesilicon senge [RP2040] kubva kuRaspberry Pi. Ini ndinofunga pane mukana wakakura pano: nekuda kwekuda kwayo kumhanya zvine hungwaru pane mapurosesa, iyo dikiML yepasi yakasundira tarisiro chaiyo pane zvakanaka zvakakwana primitives. Chinhu chinonakidza nezvenyika ino kwatiri ndechekuti inyika isingachinji maererano nezvakangoita zvekutanga, saka pane zvishoma zvekutsvagirisa izvozvi mune izvo zvinogona kuvakwa nenzira yekushandisa kuri nani, chimwe chinhu pamwe haina imwe arithmetic mashandiro pane processor processor, asi haina scaffolding yakatenderedza.
Iyo I / O chinongedzo chiripo pane imwechete bhodhi makomputa haipo pane iyo microcontroller board, chii chingave chisina kunaka. Panzvimbo iyoyo, hwaro hunopa mapeti akapetwa ane mitsetse yakasakara, sekunge kuratidza apo microcontroller iyi ingangoshandiswa zvakanyanya.
Iyo chikuva inotengeswawo muma reels ezvikamu mazana matanhatu kuti ibatanidzwe mumatanho emagetsi emagetsi Iyo nyowani microcontroller bhodhi inogadziriswa muC mutauro. Kit yekuvandudza inosanganisirwa neVisual Studio inopihwa izvi chinangwa.
Iyo Cortex M0 + haina iyo inotenderera poindi nhamba processor. Iyi ficha inobatwa kuburikidza neC yemutauro kuronga SDK. MicroPython chiteshi chinowanikwawo pakadhi rekubata Python mutauro software. Pamusangano mudiki weML Talk, maspika akaona kuti mamwe makadhi-anowaniswa magetsi anodiwa pane RP2040 chip. Saka makambani akaita seAdafruit, Pimoroni, uye Sparkfun ari kuburitsa yavo yavo Hardware, mazhinji acho aine maficha asina kuwanikwa muPi Pico.
Upton akadaro pachiitiko icho chiri-mumba Chikumbiro Chaicho IC timu Raspberry Pi (ASIC) iri kushanda pane inotevera iteration.
Mharidzo ye Upton inoratidza kuti timu yacho inoita senge inotarisisa pamagetsi anowedzera ye Ultra-yakaderera simba muchina kudzidza mashandisirwo. Munguva yehurukuro yake kuUpton, akapa slide yakanzi "Directions Directions." Iyo slide inoratidzira matatu azvino mazera "Pi Silicon" mabhodhi, maviri acho ari kubva kune vanobatana navo, SparkFun's MicroMod RP2040 uye Arduino's Nano RP2040 Connect.
Chechitatu chinobva ArduCam, inogadzira makamera anoenderana neRaspberry Pi chikuva. ArduCam parizvino iri kushanda paArduCam Pico4ML inosanganisa kudzidza kwemuchina, kamera, maikorofoni uye kuratidza mabasa mubhokisi rePico.
Iyo yekupedzisira poindi inoratidza izvo zvingave zviriko ramangwana chirongwa, icho chingauye nenzira yeanokurumidza maharisheni, pamwe 4 kusvika ku8 kuwanda kuwanda (MACs) paawa imwe kutenderera. Mukutaura kwake, Upton akataura kuti "zvinonyanya kuitika kuti pane chimwe chikamu chesilicon chinouya kubva kuRaspberry Pi."
Chekupedzisira, kana iwe uchifarira kuziva zvakawanda nezve iyi nyowani vhezheni, unogona kutarisa ruzivo Mune inotevera chinongedzo.
